A solid red boot design seems to favour the superhero aesthetic of DC Comics, further supporting the notion Injustice: Gods Among Us is headed for a 2017 sequel [full story]! Who does the boot suggest? Among the most popular fan guesses has been Atrocitus: rage fuelled Red Lantern who made a cameo appearance in the first Injustice. Also gaining traction is the often dishevelled, sometimes confused villain Bizarro.

With its unusual partially exposed toes, another possibility is a split red boot on the foot of a Doomsday mutated Superman. This would provide an alternate version of the morally corrupt Superman of the first Injustice. The Man of Steel underwent just such a transformation in DC Comics' 2014 story Superman: Doomed.

Doomed:The hero became his own worst nightmare in DC Comics' New 52.

Be it Earthbound or in distant space, the unidentified location has the trappings of a good old fashioned barroom - perfect brawling arena for the likes of Lobo. That may or may not explain the horizontal arrangement of furniture.

Does anyone have any idea what the new red boot posted on Eds Twitter means? It looks like Atrocitus, for Injustice 2. And the background looks like a bar. Iceberg Lounge for a fighting stage? Any more ideas? Could it relate to Mortal Kombat?

We know just from that pic it is definitely NOT an MKX character. There is no arena in MKX with barstools.

That said...big red boot, monstrous-looking foot.

My money's on Bizarro, or possibly even Atrocitus.

SPECULATION - lots of people on twitter are wondering if this is in fact Spawn. We know that WB has the licensing to use the character in an upcoming video game project, and it has long been rumored that Spawn would be a guest in MKX. What if he's a guest in Injustice instead?

Is that even a foot? Could even be a fist. But yeah definitely looks Injustice-y. I'd be super happy with Atrocitus as a playable character. They need to include more characters from the wider DC universe and not just limit it to Batman characters.
